Champions

January 31 - Pitcher Pud Galvin is chosen for Hall of Fame induction by the Special Veterans Committee.

July 13 - At Minnesota, Willie Mays hits a home run with two walks and two runs to pace the National League to a 6–5 All-Star Game victory over the American League. Juan Marichal pitches three scoreless innings to earn Game MVP.

September 9 - A duel between the Los Angeles Dodgers' Sandy Koufax and Bob Hendley of the Chicago Cubs was perfect until Dodger left fielder Lou Johnson walked in the fifth inning. Following a sacrifice bunt, Johnson stole third base and scored on a throwing error by Cubs catcher Chris Krug. Johnson later had the game's only hit, a 7th-inning single. Koufax's fourth no-hitter in four years is a perfect game, just the only in Dodgers history. One hit by two clubs in a completed nine-inning game is also a major league record, as is the one runner left on base. The two base runners in a game is a ML record. For Chicago pitchers, it was the second one-hitter they've threw against the Dodgers this year and lost.

September 13 - The San Francisco Giants' Willie Mays' hits his 500th home run off the Houston Astros' Don Nottebart, and Juan Marichal earned his 22nd victory as the Giants beat Houston 5-1 at the Astrodome. The win is the Giants' 11th straight and gives them a two and a half game lead.

September 26 - The Minnesota Twins gain their first American League pennant since moving from Washington in 1961, ironically by defeating the expansion Washington Senators 2-1 at Washington D.C.'s Robert F. Kennedy Stadium. Minnesota's Jim Kaat (17-11) wins the clincher.

October 7 - Jim Kaat gives Minnesota a 2-0 World Series lead by driving in two runs, defeating Sandy Koufax and the Los Angeles Dodgers 5-1 at Minnesota's Metropolitan Stadium. The game is remembered for Minnesota's Bob Allison sliding remarkable catch in the wet grass of Metropolitan Stadium.

October 14 - Working on two days rest, Sandy Koufax throws a three-hitter 2–0 shutout against the Minnesota Twins in Game Seven of the World Series, giving the Los Angeles Dodgers a second World Championship in three years. He is named Series MVP.
